High puncture strength

A shrink wrap is an incredibly strong and versatile form of plastic wrap that is used for a variety of different applications. Its high puncture strength is one of its most impressive features, making it a great choice for applications that require a very high level of resilience. 

Additionally, low-density polyethylene film is highly resistant to tears, making it a great option for applications where a secure hold is required. It’s also widely used in the packaging industry due to its ability to secure items from the elements and provide a secure, economical way to package items for shipping.

Excellent low temperature impact strength

A shrink wrap is an excellent choice for packaging and wrapping applications due to its low-temperature impact strength. It is strong and durable, making it an ideal choice for wrapping products of all shapes and sizes when it comes to cling film applications.

The linear low-density polyethylene film is also resistant to punctures and tears, providing a secure and reliable way to keep products safe during storage and transportation. In addition, it is highly flexible, allowing it to be applied quickly and easily. Its superior strength and flexibility make it a great choice for any packaging or wrapping needs.

Wear resistance

The shrink wrap is a highly wear-resistant material that is widely used in many industries. It is incredibly strong and durable, making it a great choice for protecting items from scratches, abrasions, and other forms of wear and tear. It is also highly resistant to tears, punctures, and moisture, making it a great choice for applications where protection from the elements is required.

Excellent low temperature flexibility

The shrink wrap is a plastic film that is highly flexible and stretchable at low temperatures. The film is made of linear low-density polyethylene (LDPE) resin which has been formulated to provide flexibility and stretchability at low temperatures.

The linear low-density polyethylene is designed to be used in temperatures ranging from -40°F to 120°F. This makes it an ideal choice for applications where temperatures may fluctuate and goods need to be protected.

Long retention time of wetting tension

A shrink wrap is a special type of plastic film that is often used to wrap and protect items during shipment. It is made of a polymer of ethylene and has a high degree of elongation. This allows the film to stretch and conform to the shape of the item being wrapped, creating a tight seal that provides a high degree of protection against dust, moisture, and other environmental hazards.

The long retention time of wetting tension is a key benefit of Polyethylene Stretch Film. This feature allows the film to retain its stretch capacity for a longer period of time, even after the item being wrapped is exposed to moisture. 

This polyolefin shrink wrap is particularly beneficial when protecting items from water damage or other environmental hazards, as it helps to ensure that the item is fully protected for its entire journey. Additionally, the long retention time of wetting tension can also help to create a tighter seal around the item, increasing the overall level of protection provided.

Good printing performance

A polyolefin shrink wrap is known for its excellent printing performance. The film can be printed with both solvent-based and water-based inks, allowing for a wide range of colors and designs. 

Stretch films have a higher optical clarity than other types of plastic films. This allows for clear and vibrant prints, as well as increased visibility. The film also has a glossy finish, which provides a clean, professional look to the printed product. 

Good thickness uniformity

Stretch films provide good thickness uniformity, which means it is consistent across the entire roll or sheet. This uniformity ensures that the film has consistent stretchability, which is important for efficient cast extrusion process and maximum protection of the products being packaged. 

The uniformity also helps the film perform better in various applications, such as pallet wrapping, bundling, and wrapping irregularly shaped products. With uniform thickness, the stretched film applications are less likely to tear or break during the application, helping to protect the products more effectively. 

The uniformity of the low-density polyethylene film also enables effective resource management because it can be applied in the same amount of time regardless of the product’s size or shape.

High tensile strength

One of the primary advantages of polyethylene cast stretch films is its high tensile strength. This means that the film can be stretched to a certain point and will still retain its shape and strength, even when it is stretched beyond its original size. The stretch films make the ultra low density polyethylene ideal for wrapping items that need to be tightly secured and protected while in transit or storage.

The high tensile strength of polyethylene films make it the excellent choice for protecting items from shock, vibration, and other types of physical damage. The polyethylene films are also highly resistant to moisture, which makes them useful for keeping items dry in humid environments. 

The LLDPE stretch films are also highly resistant to punctures, tears, and other forms of damage, making it an ideal choice for protecting fragile items such as electronics, food, and other fragile items. The high tensile strength of polyethylene stretch film also makes it a great choice for use in wrapping irregularly shaped or oversized items, as it can be stretched to fit them perfectly. 

Benefits of Using Polyethylene Stretch Film

Secure Packaging

Blown stretch films provide excellent protection for various types of products during shipping and storage and is a cost-effective and environmentally friendly way to secure items for transport. The film is created by taking polyethylene and stretching it under specific conditions to create a thin film. 

The LLDPE stretch films are typically used to wrap pallets or packages and is secured with a heat sealer, tape, or other fastening devices. The film can be used to help protect products from dust, moisture, scratches, and other damage. 

Additionally, it provides an extra layer of security that can prevent tampering or theft of the product. The LLDPE stretch films have tear resistance feature making it an excellent choice for securing items that may need to be handled multiple times during their shipment.

Cost Effective Solution

Polyethylene stretch film is also cost-effective, as it is much cheaper than traditional packaging materials such as cardboard and bubble wrap. It is also recyclable and reusable, making it an environmentally friendly option. 

The LLDPE stretch film can help improve product protection. By securely wrapping items, they are less likely to be damaged during transit. This can help reduce the number of damaged goods, which reduces the cost of returns and refunds. 

Improved Productivity

The use of polyethylene stretch film has been shown to improve productivity in a variety of ways. The use of stretch film reduces the amount of time and effort needed to package and ship items. By wrapping items with stretch film, items can be securely wrapped and stabilized quickly. This reduces the amount of labor needed to package items, saving time and money. 

The stretch film can help increase the speed of warehouse operations. By wrapping items with stretch film, they can be picked and scanned more quickly, as it improves the warehouse’s effectiveness. 


In conclusion, polyethylene stretch film is an effective and economical packaging material that offers a variety of benefits such as high tear resistance, excellent puncture resistance, high clarity, and a secure seal.
